LOCOMOTlVE-C AB SEAT.

SPECIFICATION forming part of Letters Patent No. 594,792, dated November30, 1897. Application filed May 23 1892. Serial No. 433,992. (No model.)

To all whom it may concern: 7

Be it known that I, AUSTIN I. I-lARvEY, a citizen of the United States,residing at Newport, in the county of Penobscot and State of Maine, haveinvented a new and useful Lo comotive-Seat; and I do hereby declare thatthe following is a full,clear, and exact description of my invention,which will enable others skilled in the art to which it appertains tomake and use the same.

Throughout the description reference is made to the accompanyingdrawings, forming part of this specification, and the letters ofreference thereon, in which- Figure 1 represents a perspective view ofmy improved locomotive-seat complete. Fig. 2 is a side elevation of thesame. Fig. 3 is a perspective view of the base of my device as usuallymade with the ends of hangers connected to terminals of the end springs.Fig. 4 shows an end view of my improved seat, showing relative positionof its different parts. Fig. 5 is a perspective view of the seatcomplete, but showing a different form of springs from that shown inFig. 1. Fig. 6 shows a like view of the clips of my invention used inattaching the springs of my device.

Similar letters of reference refer to correspondin'gly like partsthroughout the several figures.

The main object of my invention is to overcome the side motion andlurching of railwaylocomotives which is apparent when running and iscaused more conspicuously when rounding curves,running over frogs andopen rail-joints, and other imperfections in the track.

It is therefore the object of my invention to overcome the difficultiesattending a locomotive-engineers position by producing an oscillating orlaterally-swinging engineers seat that will when occupied practicallyremain stationary and allow the engine to vibrate from under the samewithout transmitting any of the motion to the sitter thereon.

Inthe drawings, A represents the bottom board of my device,which is madeof sufficient size to cover the top of the usual tool-box carried bylocomotive-engineers. To the ends of the bottom board A, I attachupright cleats h h and confine the crank ends of hangers O G(hereinafter to be described) in bearings it,

the springs and a single confining-bolt securing each spring to the saidcleatsbetween the clips. This provides a metallic contact for thebearings of the springs e e and prevents their wearing away the wood ofthe cleats b b by continuous use. The clips t' t' furthermore preventthe springs from turning upon their pivotal connection and the leaves ofthe same from separating. In order to increase or diminish theflexibility of the springs e e,

it is only necessary to unscrew their single confining-bolts and takefrom or add the number of leaves desired.

The hangers O O of my device, which are two in number, are constructedfrom round material of sufficient length to extend the entire distanceunder the seat B and turn up at each end thereof into crank shape,projecting in equal and similar planes. The terminals of the hangers O Oare adapted to turn in the bearings n at the ends of the springs e e. Asthe seat is swung laterally the hangers are also adapted to turn in thejournal-boxes 25 t, that are secured to the seat, preferably on theunder side, in such manner that the hangers lie in planes inclinedtoward each other. By the inclination of the hangers O G, I limit theside movement or oscillation of the seatB without producing a jar uponthe latter when swinging to its greatest extent and, furthermore,preventthe hangers from swinging completely over when my device is turnedupside down, as it would often be when hinged to the top of a tool-box.

The seat B of my device is composed of a "board of su'fficient-sizehighly upholstered,

with helical springs and padding. A back D, also upholstered, isattached to the seat B by means of an intermediate spring connection fat one end thereof. i

It can now be readily understood with my device as thus described thatall side jar is overcome by the swinging of the seat, or, rather,

the movement of the base is overcome by the action of the crank ends ofthe hangers O 0, attached to the seat, as the latter will remainpractically stationary. The hangers C could be merely cranks attached tothe ends of the springs e and bottom of seat and not extend the entirelength of the latter and the operation would be the same, but withcontinued use they would soon wear loose in their journal-boxes andcease to operate perfectly.

Having thus described my invention and the manner in which it is used,what I claim, and desire to secure by Letters Patent of the UnitedStates, is-

1. A laterally swinging locomotive seat consisting of a seatproperprovided with longitudina-lly-extending crank-hangers having theircrank-shaped ends attached to the extremities of lateral springs andlateral springs having their free ends adapted to receive the ends ofthe crank-hangers, and a base having means for connecting said springsfor the purpose described and substantially as shown and set forth.

2. A locomotive-seat consisting of the combination of arectangular-shaped seat; an upright back connected thereto at one end bya spring; longitudinally-extending rods having crank-shaped ends passingunder said seat and having their extremities connected to springs insuch manner as to allow lateral swinging of the seat in a horizontalposition;

and a base-board extending under said scat upright cleats for attachingthe springs thereto, lateral springs interposed between thecrank-hangers and said cleats all for the purpose described andsubstantially as set forth.

3. An improved locomotive-seat consisting of the combination of abase-board having AUSTIN I. HARVEY.
